4 Our invention relatesto new and; useful improvements in buttons, andmorepartiew larly to a button of the shell type in which there issecurelyfastened a viceor, die' into 5 which the fastener is to beVdriven tothereby hold: theV button' tightly in place. 4

' "Gne ofthe principal objects Vof the invention is to produce a buttonof the shell type whichwill be extremely light in weight, in

that itis notv necessary toprovide an eXtra anvil to fill up the spacebetween the rim of the button and its top or cap.

Still another object of the invention is to provide a button of theshell type in which there is fastened a small die and which die, inturn, is tightly secured in place, so that when the button shell and dieare being tuinbled around in the hopper of an assembling machine thereis no possibility of the die 20 dropping out of its shell.

Still another object of the invention is to produce a button whereinthe` die can be forced into the hub of the shell of the button up to itsshoulder and will tightly remain in position a ter being placed in thehub and the top of the die will act as a reinforcement for the top orcap of the button.

Still another object of the linvention is to produce a button consistingof a shell, a small V die with the shoulder and a cap, and the buttonhub and die so indented that the die, after once being so acted on, willalways remain properly and rigidly fixed within the hub of the shell. yWith these and other objects in view, theV invention consists in certainnew and novel arrangements and combination of parts, asv

will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment,

Fig. l is an enlarged side elevation, bottom plan, and cross section ofthe little die; Fig. 2 is an enlarged top plan view of the button shell;

Fig. 3 is a sectional View thereof taken on the line 3--3 of Fig. 2;

ing the hub of the button head and the die to rigidly hold the die inplace g- Fig. 5 is a sectional view of the assembled button' and showingthe taclrto rigidly hold I the button to the cloth. Y

Referring now more particularly tofthe several views, there is shown inFigs 2 and 3a button' shell l comprisingthe hollow inte'gral hub'pQ',the outwardly'extending body portion: 3' and' the upwardly and outwardlyrim il. This' shell is of?v the perfora-t'e type, that is,thebottorn'is'pi'erced, 'as at, this` openingl assisting inr guiding theprong Grofa taci; fastener 7: into itsfinalzposition, as will be shortlyexplained.` Y

Referringnow more particu'larly'to Figi, there i'snshown the smallviceor'die 8 which has a' substantially vertical outer/peripheral wall. 9,'a shoulder' lO,and the' integral top'l'l. The bottom surface` l2 of thedie is split radially,.as-at' 13, and is indented or perforated, yas at14, the little jagged ends of metal`A l5 being; clearly Seen'A in the"sectionall view lof Fig. l1.Y This little circular 'die' yis thendriven'within theV hollow hubV 2 of the' shell, and it will-be' lnoticed thatthe height of the vdie from theshculder l0 to andincluding the top`surface of.' itsY cover-ll is 'now'flush with the upper peripheral edgeof the rim/4 ofthe button'. f

When the `die is jammed within the hub', as before mentioned, thevtwoperforatedbottomportions 5 and 14C are now in alignment andwi'llraprpearV as shown in Fig; 4;'.

f To* rigidly hold this diein place, so'that there is no possibility ofits dropping. out when tumbled around in thehopperof an .asseinblingmachine, the partly assembled .button is-placed'in a vice l(not shown),while oppositely, extending. punches 16' with the little' points-17thereon will be driven inwardly towards each other to'indent the hub,

We have not shown the mechanism for forcing these little punches 16inwardly, but it will be understood that the buttons will beautomatically fed into a machine and these buttons and hubs indented ina very rapid manner.

After the die has thus been rigidly fastened within the hub of thebutton shell, a cap 2O of usual form may be tightly crimped, as at 21,over the outwardly flared rim l of the button. Of course, this buttoncap may have any desired insignia thereon or any fanciful design. Y

It will also be noticed that when the cap 20 is placed in position, theupper surface l1 of the die will act as a backing for the cap during itscrimping operation and will also rigidly hold the cap in place duringthe life of the button and prevent the cap from being forced or sagginginwardly.

When the buttons are attached, the button heads l will be placed in theordinary button fastening machine and the button heads fed from onehopper and the tacks from another hopper (not shown) and the prong 6will be driven into the hub of the button shell and die and will bemutilated, as shown in Fig. 5, the upper surface 1l of the die turningthe prong of the tack or fastener and the button will thus be rigidlysecured to the cloth 22, as shown in Fig. 5.

From the foregoing, it will be seen that we have produced a shell buttonwhich is extremely simple in construction and exceedingly light inweight. Finally, the little die will remain in its proper set positionand will deflect the prong of the fastener when being attached to thecloth and rigidly support the cap, thus saving the expense of an anviland holding the button down to a minimum weight.

Having thus described our invention, what we claim and desire to secureby Letters Patent is 1. A button comprising a hollow shell, an integralhub, a die fitting within said hub, a cap over said shell and die, themetal of the hub of the button shell having small dents formed therein,and the metal displaced by said dents itting within resultant dents inthe die to thus rigidly hold the die within the hub.

2. A button comprising a hollow shell and an integral hollow hub, a diefitting within the hub, a shoulder on said die and overlying theperipheral upper edge of the hub,

metal tightly fitting within the hub, a shoulder on said die overlyingthe peripheral edge of the hub, a cap on the button shell, the metal ofthe hub deformed at a plurality of' points about the hub just belowwhere the hub merges with the shell, complementary indentations in thedie receiving the displaced metal of the hub to thus rigidly hold thedie within the button shell.

4. Arbutton comprising a hollow shell and an integra-l hub, a diefitting within said hub, the bottom of the die being radially split andperforate, the bottom of the hub of the button shell also beingperforate, a shoulder von said die and overhanging the peripheral edgeof Vthe hub of the button shell, a cap on said shell and contacting withthe upper surface of the die, and pointed indentations formed inthe hubof the button shell and extending into the walls of the die to rigidlysecure the die in the button shell.

In testimony whereof we aflix our signatures.
